yWILLIAM SHAW, OF HUDSON, NEW YORK.

IMPROVED ADJUSTABLE WINDOW-STOP.

Specification forming part of Letters Patent No. 49,660, dated August29, 1865.

To all whom it 'may concern:

Be it known that I, WILLIAM SHAW, of Hudson, in the county of Columbiaand State of New York, have invented a new and Improved Mode ofConstructing Vindow-Stops; and I do declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of-this specification.

Figure l is a perspective view of the stop in place. Fig. 2 is a view ofthe slotted metallic box detached from the stop, and of the screw A,used for fastening the stop to the window-jamb. Fig. 3 represents thescrewsocket nut and screw-fastener A.

The nature of my invention consists in providing window-stops with smalltransverse slotted apertures in metallic boxes or linings, throughwhich, by means of a screw of proper size and construction to allow thestop to be easily adjusted to or from the sash, it is fastened rmly tothe jauib.

To enable those skilled in the art to make and use my invention, l willproceed to describe its construction and operation.

I construct my window-stop in the ordinary form, and wherever it isdesired to fasten it to the jamb-casing I bore a halt-inch hole andinsert a small metallic box, which is provided with a slotted aperture,(see Fig. 2,) the elongation of the slot being placed crosswise of thestop. In some the slot is at the outer or upper end of the box, andinserted to be even with the surface of the stop. In others it is at thebottom or inner end, or so deep as to bring the head ot' the screw evenwith the outer face or surface of the stop. This lastdescribed box is ofcourse enough larger not only to admit the head of the screw, but toallow the stop to be adjusted as required. These boxes are all providedwith a slight rim or flange on the outer margin to prevent being drawninto the wood, and also a slight rib running from top to bottom toprevent their turning or revolving in the hole.

'Ihe size ot' the head of the screw A should be such as to cover theslot B in any position.

I sometimes employ simply a metallic lining to the slot, cutting theelongated or elliptical aperture transversely through the stop, andinserting therein a brass, iron, or other metallic lining to preservethe elliptical form of the aperture. It may also be used without box orlining.

It is the transverselyelon gated or elliptical aperture in the stop,employed in combination with a properly constructed screw, that enablesthe stop to be adj usted to suit the circumstances or condition of thesash or the pleasure of the occupants of the house, and also to keep itfirmly in its place.

rIhe screw A is comparatively slender, while its head is large and atbeneath, being hemispherical or oval above, and ornamented or plain-thatis, of iron, brass, or silver-or painted like the casings.

I also use in first-class work screw-socket nuts, or matrices withscrew-thread on the outside to screw into the jamb-casing, and withthread like a nut inside to receive the screw A instead ot' its enteringonly the wood. (See Fig. 3.) This is to prevent the wear and tear ot'the wood ofthe casing, and the consequent loosening of the stop.

The slotted boxes being round are fitted into a round hole in the stopwith the slot crosswise, the screws inserted through the same into thejamb-casing or socket-nut, Fi0u3,and the stop adjusted as required andthen firmly fastened.

When windows have been newly painted it frequently happens that it isimpossible to elevate the sash without removing the stopstrips, one orboth; or, it' allowance has been made for this when the stops were iirstnailed on, the sash soon becomes so loose. that every hard wind hauntsthe house with their inces sant rattling, and an extra quantity ot' fuelis required to keep at all comfortable within. The adjustable stop isdesigned to avoid these ditoulties.

I am aware that similar devices are used on some kinds of tools forguides, and in some machines forv the same purpose, but in most casesfastened by thumb-screws. I am not aware that they were ever applied forthe purpose or in the manner herein described-that is, for the purposeof making window-stops ad justable.

What I claim, therefore, and desire to se= cure by Letters Patent of theUnited States,

The box or thimble, with opening or slot B, inserted into the stop orbead, and through which slot B the screw A passes into the jamb, wherebythe said bead or stop is made adjustable relatively to the sash, inorder to maintain the requisite fit or tightness, as described.
